Add User To SharePoint Group Programmatically with STSADM, C# and PowerShell

Apart from SharePoint User Interface, We can programmatically add users to SharePoint group or site in these ways:
  • Using STSADM command line tool to add users 
  • Add users to Sharepoint site/group using C# Object Model
  • Add users to SharePoint Group using PowerShell

1. Using STSADM command line tool to add users:
To add user to the SharePoint site, we can use stsadm classic command line tool.  bulk users to add from a CSV file:
  • Add user to a SharePoint group:
    stsadm -o adduser -url "http://sharepoint.crescent.com/sites/marketing" -userlogin crescent\UserName -useremail UserName@crescent.com -group "Marketing Members" -username "User Name"
  • To Add a User directly user under "Site Permissions"
    stsadm -o adduser -url "http://sharepoint.crescent.com/sites/marketing" -userlogin crescent\UserName -useremail UserName@crescent.com -role "Full Control" -username "User Name"
  • To Add a user as Site collection Administrator:
    stsadm -o adduser -url "http://sharepoint.crescent.com/sites/marketing" -userlogin crescent\UserName -useremail UserName@crescent.com -group "Marketing Owners" -username "User Name" -siteadmin
Stsadm -o Adduser operation Technet reference: http://technet.microsoft.com/en-us/library/cc262627.aspx


2. Add Users to SharePoint Programmatically using C# :

Adding users to SharePoint site programmatically: Here is how we can add users to SharePoint site With .Net Object Model C# Code. (This works both in SharePoint 2007 and SharePoint 2010)
    using(SPSite site=new SPSite("http://sharepoint.crescent.com"))
            using (SPWeb web = site.RootWeb)
                 string GroupName="SharePoint Members";
                 SPGroup group = web.Groups[GroupName];
                        //To Get the Default Members group
                        //SPGroup group = web.SiteGroups.Web.AssociatedMemberGroup;
                 SPUser user = web.EnsureUser("Crescent\\Salaudeen");

3. Add User to SharePoint 2010 using PowerShell Cmd-lets:
New-SPUser -UserAlias "domain\user" -Web "http://sharepoint.crescent.com/sites/marketing" -Group "Marketing Owners"
This will create a add a new User to SharePoint site to the particular group. If you execute this command for the next time, (without deleting the user from site collection) this command has no effect!

Set-SPUser -Identity "domain\user" -Web "http://sharepoint.crescent.com/sites/marketing" -Group "Marketing Owners"
This will add existing SharePoint users account to the provided group, but will give error when you try add a new user to SharePoint site. (which is obvious! We can't set the user property, if the user doesn't exists in SharePoint site, isn't it?)

Add User to SharePoint Group using PowerShell

#Get the Web
$web=Get-SPWeb "http://sharepoint.crescent.com/sites/marketing"
#Get the Group
$Group= $web.Groups["Marketing Owners"]
$userName = "domain\userName"

#Add User to the site collection
$user = $web.EnsureUser($UserName)

#Add User to the Group
